Depicts harbour sunlight (8)
I believe the answer is:
portrays
'depicts' is the definition.
(I've seen this before)
'harbour sunlight' is the wordplay.
'harbour' becomes 'port' (I've seen this before).
'sunlight' becomes 'rays'.
'port'+'rays'='PORTRAYS'
(Other definitions for portrays that I've seen before include "Depicts" , "Shows" , "Represents" , "paints?" , "Describes in words or makes picture of" .)
